Horizontal Sliders Lock

Aluminum or vinyl windows have a sliding half side with a hinged catch that is locked onto the frame of the window. In some, the other side of the window may also have a sliding catch that locks to a depressed bottom track. Knowing how to open the horizontal sliding windows means releasing the two locks of the window.

Furthermore, the inbuilt springs help the window to lock automatically. If you don’t know this, you may release only one catch and wonder why the window is not opening.

The pivot locks of the horizontal sliding windows can get stuck sometimes because of one of the two windows moved out of track. To Fix this, lift the window and turn the pivot with one hand to unlock it.
